For the purpose of securing users data, Apple has quickly unveiled the iOS 11.4.1 update for eligible iPhone, iPad, and iPod touch models. Among other tweaks, the latest iOS update brings an anticipated safety feature – by default, your iOS device will prevent USB accessories from connecting more than an hour after it was locked.

This change addresses the issue that was letting law enforcement and private companies crack the passcode through the Lightning port with brute force methods. Apple representatives said that the change in the settings would protect customers in countries where law enforcement seizes and tries to crack phones with fewer legal restrictions than under US law. “We’re constantly strengthening the security protections in every Apple product to help customers defend against hackers, identity thieves and intrusions into their personal data,” Apple also stated, “We have the greatest respect for law enforcement, and we don’t design our security improvements to frustrate their efforts to do their jobs.”

In other to restrict USB access, the iOS 11.4.1 brings a new toggle for USB Accessories that you can find by going to Settings > Face ID (or Touch ID) & Passcode.

The option is by default disabled. This enables you to disallow USB accessories to establish a connection with your iOS device if it has been locked for over an hour. Also, cracking tools such as GrayKey will not be able to gain backdoor access to your device. However, if you own an USB accessory that you want to continue work with your iOS device for over an hour, you can toggle the USB Accessories option on and it will remove the hour limit.

Additionally, iOS 11.4.1 fixes an issue that prevented some users from viewing the last known location of their AirPods in the Find My iPhone app. The update also improves the reliability of syncing mail, contacts, and notes with Exchange accounts.
